New alt. not putting out enough volage, suspect other issues?

The inter-relationships between electrical devices on these trucks is sometimes quite mysterious...... Solve one problem at a time. Sometimes, fixing one problem, solves a whole bunch of others as well.
Got a volt/ohm meter? Could pull the relay, disconnect the a/c compressor, and then test the wire, see if it goes directly to ground.

Sounds as if you shorted something upon reconnection OR the battery or alternator are bad...circumstantial evidence is evidence of just that

Pay attention to WHEN the fuse blows, if it goes as soon as the the a/c is turned on, even with the compressor disconnected, then its a wiring problem. If it blows when you plug in the compressor, time for a new compressor clutch.
